  A projector, which is a type of display device in the present embodiment, normally projects a moving image. However, when a user instructs the viewing environment setting, the projector combines the moving image and the viewing environment setting OSD image. Display an image.

  FIG. 1 is a diagram illustrating an initial state of a composite image 300 in the present embodiment. FIG. 2 is a diagram illustrating an intermediate state of the composite image 300 in the present embodiment. FIG. 3 is a diagram illustrating a final state of the composite image 300 in the present embodiment.

  As shown in FIGS. 1 to 3, the projector displays the composite image 300 so that the OSD image 310 becomes gradually transparent (the transmittance increases) according to the display elapsed time. Accordingly, even when the user repeatedly sets the viewing environment using the OSD image 310, the user can set the object 320 or the like included in the moving image without missing it.

  Next, functional blocks of projector 100 having such a function will be described.

  FIG. 4 is a functional block diagram of the projector 100 in this embodiment.

  The projector 100 functions as an input unit 130 that inputs user instruction information, an image information input unit 140 that inputs image information, a processing unit 110, a storage unit 120, and a display unit that displays the composite image 300. Part 150.

  The processing unit 110 also includes a timer unit 111, a determination unit 112 that determines the content of the instruction information, a transmittance setting unit 113 that sets the transmittance of the OSD image 310, and an image generation unit 114 that generates the composite image 300. It is comprised including.

  In addition, the storage unit 120 stores OSD image data 121 for generating the OSD image 310, OSD setting data 122 indicating the setting of the OSD image 310, environment setting data 123 indicating the setting value of the viewing environment, and the like.

  Here, the data structures of the OSD image data 121 and the OSD setting data 122 will be described.

  FIG. 5 is a diagram showing a data structure of the OSD image data 121 and the OSD setting data 122 in the present embodiment.

  The items of the OSD image data 121 correspond to, for example, “ID” that is identification information, “item” that indicates a setting item, “image data”, and the like.

  The items of the OSD setting data 122 include, for example, “ID” that is identification information, “item” that indicates a setting item, “state” that indicates a display state, “transmittance” that indicates the transmittance for each item, and display “Position” indicating the position corresponds to this.

  The items used as the OSD image data 121 and the OSD setting data 122 are not limited to the example illustrated in FIG. 5, and may be added, changed, or deleted according to the form to be used. For example, “item”, “state”, and “position” are not essential.

  Each unit such as the determination unit 112 may be configured using the following hardware, for example.

  For example, the input unit 130 is a button for direct input, an infrared interface for indirect input that receives infrared light from a remote controller, the image information input unit 140 is a commonly used input / output interface, or the like, and a timer unit 111. Is a system timer, the determination unit 112, the transmittance setting unit 113 is a CPU, the image generation unit 114 is an image processing circuit, the projection unit 150 is a lamp, a liquid crystal panel, a projection lens, a driver, and the storage unit 120 is a RAM. May be configured.

  Further, the function of the determination unit 112 or the like may be implemented in the computer by reading the program from the information storage medium 200 storing the program for causing the computer to function as the determination unit 112 or the like.

  As such an information storage medium 200, for example, a CD-ROM, DVD-ROM, ROM, RAM, HDD or the like can be applied, and the program reading method may be a contact method or a non-contact method. Good.

  Instead of the information storage medium 200, the functions described above can be implemented by downloading a program or the like for implementing the functions described above from a host device or the like via a transmission path.

  Next, the flow of processing in OSD image display using these units will be described.

  FIG. 6 is a flowchart showing a flow of processing in OSD image display in the present embodiment.

  The input unit 130 inputs instruction information indicating an instruction to display the OSD image 310 by a button operation or a remote control operation by the user. The determination unit 112 determines the content of the instruction information, the image generation unit 114 generates a composite image 300 including the OSD image 310, and the projection unit 150 displays the composite image 300 including the non-transparent OSD image 310. (Step S1).

  In the present embodiment, the projector 100 displays the OSD image 310 with the transmittance set to the minimum value in the initial state, but according to the display elapsed time (the elapsed time since the transmittance was set to the minimum value). Increase the transmittance step by step.

  FIG. 7 is a diagram illustrating an initial state of the OSD image 311 in the present embodiment.

  More specifically, the OSD image 311 is an image of a projector environment setting menu. The setting items of the top menu of the configuration menu include, for example, “image quality adjustment” for adjusting the brightness of the image, “video” for adjusting the display position, size, etc. of the image, keystone correction, volume, etc. For example, “setting” for adjusting the lamp, “expansion setting” for setting the standby mode, “initialization” for initializing the lamp lighting time, and the like.

  Each top menu is provided with a submenu, and the user performs various settings on the submenu. For example, submenus such as “color mode”, “brightness”, and “contrast” are provided in “image quality adjustment” in the top menu.

  Based on the instruction information from the input unit 130, the determination unit 112 determines whether there is an instruction from the user while the OSD image 310 is displayed (step S2).

  Further, when the instruction is given, the determination unit 112 determines whether the instruction is to end the display of the OSD image 310 (step S3).

  If it is a display end instruction, the projector 100 ends the display of the OSD image 310. On the other hand, when it is not a display end instruction, that is, when it is a setting instruction, the determination unit 112 updates the environment setting data 123 and the OSD setting data 122 according to the setting instruction (step S4).

  For example, in a state where the OSD image 311 shown in FIG. 7 is displayed, when the user performs an operation of setting “brightness” of “image quality adjustment”, the determination unit 112 determines “brightness” of the OSD setting data 122. “Transmittance” is set to “50”, and “Transmittance” of other items is set to “100”. Note that the processing related to the environment setting data 123 is a conventional processing, and a description thereof will be omitted.

  The projection unit 150 displays the OSD image 310 based on the OSD setting data 122 (step S5). Note that various commonly used techniques can be adopted as a technique for changing the image transmissivity. For example, a transmissive display function implemented in the display CPU of the projector 100 may be adopted. .

  FIG. 8 is a diagram illustrating an intermediate state of the OSD image 312 in the present embodiment.

  For example, when the user performs an operation for setting “brightness” in “image quality adjustment”, the transmittance of “brightness” is 50% and the transmittance of other items is 100%. As shown in FIG. 6, in the OSD image 312, only the “brightness” submenu is visible.

  When a predetermined time (for example, 5 seconds to 1 minute) elapses without an instruction from the user after the OSD image 310 is displayed, the determination unit 112 determines the OSD image 310 based on the OSD setting data 122. It is determined whether or not the transmittance is maximum (step S7).

  When the transmittance of the OSD image 310 is not the maximum, the transmittance setting unit 113 updates the OSD setting data 122 so that the transmittance increases (step S8).

  In this embodiment, the transmittance setting unit 113 updates the OSD setting data 122 so that the transmittance increases step by step to 50, 60, 70, and 80 (maximum).

  Then, the projection unit 150 displays the OSD image 310 based on the OSD setting data 122 (step S5).

  When the transmittance of the OSD image 310 reaches the maximum (80% in this embodiment), the OSD setting data 122 is not updated (step S8). In addition, when there is an instruction from the user in a state where the transmittance of the OSD image 310 is increasing, the determination unit 112 sets the OSD setting data 122 so that the transmittance of the item being set is set to the minimum value. Update (step S4).

  As described above, according to the present embodiment, the projector 100 can gradually make the OSD image 310 transparent by increasing the transmittance of the OSD image 310 according to the display elapsed time of the OSD image 310. . Further, the projector 100 can immediately reflect the setting of the viewing environment in the OSD image 310 in the composite image 300. Thus, even when the user repeatedly performs viewing environment settings such as image brightness adjustment, the setting is easy, and the projector 100 can further improve the operability of viewing environment settings.

  In addition, according to the present embodiment, the projector 100 displays the OSD image 310 in a state where the moving image can be confirmed, so that the user can perform settings using the OSD image 310 without missing the moving image. That is, even when the user adjusts the brightness or the like in a bright scene or a dark scene, the user views the moving image with the OSD image 310 displayed while waiting for the scene, and becomes the scene. The brightness and the like can be adjusted immediately in the event of a failure.

  In addition, according to the present embodiment, for example, even when the projector 100 switches from the image information from the DVD player to the image information from the set top box of the cable TV, the OSD image 310 remains displayed. Therefore, even when the moving image is switched, the user can immediately adjust the brightness or the like according to the new moving image.

  Further, according to the present embodiment, the projector 100 can prevent the OSD image from becoming completely transparent as in the related art by not setting the transmittance to 100%. Thus, even when the user repeatedly performs viewing environment settings such as image brightness adjustment, the setting is easy, and the projector 100 can further improve the operability of viewing environment settings.

  Further, according to the present embodiment, when the projector 100 is instructed by the user, the user can easily confirm the OSD image 310 by immediately returning the transmittance to the initial state. Thus, even when the user repeatedly performs viewing environment settings such as image brightness adjustment, the setting is easy, and the projector 100 can further improve the operability of viewing environment settings.

  Further, according to the present embodiment, as shown in FIG. 8, the projector 100 displays the OSD image 312 with the latest setting item set by the user in a non-transparent state and items other than the setting item in a transparent state. Thus, the display ratio of the OSD image 310 in the composite image 300 can be reduced, and even when the OSD image 310 is set, the moving image can be displayed more easily. Moreover, according to this, since the display device or the like can display only the latest setting items by the user, the user operability can be further improved.

  In addition, application of this invention is not limited to the Example mentioned above, A various deformation | transformation is possible.

  For example, the projector 100 may display not only the latest setting items but all set setting items.

  FIG. 9 is a diagram showing a composite image 301 displaying a plurality of setting items in the present embodiment.

  For example, when the user adjusts “brightness” and “trapezoid correction”, as shown in FIG. 9, the projector 100 displays an OSD image 313 of “brightness” and an OSD image 314 of “trapezoid correction”. Also good. In addition, as illustrated in FIG. 9, the projector 100 may adjust the positions of the OSD images 313 and 314 in accordance with a user instruction.

  Note that the determination unit 112 sets “brightness” and “transmittance” and “position” of “trapezoid correction” in the OSD setting data 122, whereby the projector 100 sets the OSD images 313 and 314 in the composite image 301. The position can be adjusted.

  Further, when displaying a plurality of moving images in one image, such as a parent-child image or a multi-image, the projector 100 may display setting items for each of the plurality of moving images.

  FIG. 10 is a diagram illustrating a composite image 302 that displays setting items for each of a plurality of moving images 330 and 331 in the present embodiment.

  For example, the projector 100 displays the composite image 302 including the OSD image 315 for adjusting the moving image 330 and the OSD image 316 for adjusting the moving image 331.

  According to this, even when the projector 100 displays a plurality of types of moving images 330 and 331 at the same time, the user can set the viewing environment for each moving image, thereby improving the operability for the user. be able to.

  In this case, for example, in the OSD setting data 122, the item “ID” for the OSD image 315 may be provided in the 1000s, and the item “ID” for the OSD image 316 may be provided in the 1000s. For example, “ID” of “brightness” of the OSD image 315 is “1120”, and “ID” of “brightness” of the OSD image 316 is “2120”. By configuring the OSD setting data 122 in this way, the determination unit 112 can manage a plurality of OSD images 315 and 316 simultaneously.

  Further, the projector 100 may display an image other than the menu image for setting the viewing environment as the OSD image 310.

  FIG. 11 is a diagram illustrating a composite image that displays the current date and time in the present embodiment.

  For example, the projector 100 may display a composite image 303 including an OSD image 317 indicating the current date and time, as shown in FIG.

  According to this, the user can confirm the current date and time without missing the contents of the moving image. In particular, in the case of the projector 100, since the surroundings are dark, it is difficult for the user to check the time and the like with a clock. However, by displaying it as a part of the composite image 303, the user can easily check the current date and time. Can be confirmed. Note that the OSD image 317 may be an image indicating only the date and only the time, not the date and time.

  Further, the transmittance may not be set stepwise, and may be continuous (for example, the transmittance changes to 50, 51, 52, etc.). Further, the minimum value of the transmittance is not limited to 50, and may be 0, for example. Further, the maximum value of the transmittance is not limited to 80, and may be 99, for example.

  As the projector 100, various projectors such as a liquid crystal projector, a projector using a DMD (Digital Micromirror Device), a CRT projector, and the like can be adopted. DMD is a trademark of Texas Instruments Incorporated.

  The display device is not limited to the projector 100, and various display devices such as a projection TV, a liquid crystal TV, a liquid crystal display, a portable game device, a mobile phone, and a PDA can be employed.

  The display device is not limited to a single device, and the function of the display device may be distributed to a plurality of devices. Specifically, for example, a part of the functions of the display device may be mounted on the PC and other functions may be mounted on the liquid crystal display.
